How to complaint alexa.com's support about top-1m.csv?

Hi guys,
I met a problem, this problem has lasted for 22 days,since 30/1/2017.
Everyday so many sites(100,000) no ranks or out 1m ranked in top-1m.csv now.
Some sites just one parkingpage,some sites even not registered.
So i submit a request to alexa.com's support,
But they rather have been closed my problems, but not to solve their problem.
I'm going to complain to their work,some one know how to complaint ?
The top-1m.csv data is not accurate now.

I registered a .com for test just a parkingpage,and it into top-1m.csv now.
This is a joke, because this domain name is definitely no traffic.
